`toupper'--translate characters to upper case
int toupper(int C);
int _toupper(int C);
`toupper' is a macro which converts lower-case characters to upper
case, leaving all other characters unchanged. It is only defined when
C is an integer in the range `EOF' to `255'.
You can use a compiled subroutine instead of the macro definition by
undefining this macro using ``#undef toupper''.
`_toupper' performs the same conversion as `toupper', but should
only be used when C is known to be a lowercase character (`a'-`z').
`toupper' returns the upper-case equivalent of C when it is a character
between `a' and `z', and C otherwise.
`_toupper' returns the upper-case equivalent of C when it is a
character between `a' and `z'. If C is not one of these characters,
the behaviour of `_toupper' is undefined.
`toupper' is ANSI C. `_toupper' is not recommended for portable
No supporting OS subroutines are required.
